To @ZZ whom it may cof/wem: Be it known that l, GEORGE GRTGIER, a citizen ofthe United States, and resident of East St. Louis, and State of illinois, have invented certain new and useful improvements in Aeroplanes, of which the following is a specication containing a full, clear, and exact description, references being had to accompanying drawings, forming a part thereof. i j

My invention relates to improvements 1n aeroplanes, andhas for its .primary object the construction `of an aeroplane which 1s provided with a steering plane at its rear end, and which may be controlled or adjusted to direct the Vplane in any direction.

In the drawings:

Figure 1 isa top -plan view of my 1mproved aeroplane.

Fig. 2 is a side elevation of the rear portion thereof, parts being in section.

Fig. 3 -is a rear elevation, showing the steering plane in its maximum adjustment while the'plane is in flight for descending toward the right. Y

Fig. 4 is the rear elevation of the machine in flight, and illustrating the steering plane in its maximum adjustment, ascending toward the right. 5

Fig. 5 is the top plan View with parts broken away, illustrating the position of the steering lever when the steering plane 1s adjusted, as illustrated in Fig. 3.

Fig. 6 is a similar view illustrating the steering lever when .the steering planel is in the adjustment as illustrated in Figi.v 4.

Fig. 7 is a transverse section taken on the line 7-7 of 1, when the guiding plane is extended and in use.

Fig. 8 is a similar view, illustrating the guiding plane in inoperative position.

Fig. 9 is a transverse section, taken on the line 9-9 of Fig. 2, and Fig. 10 is a side elevation of the steering lever and the parts to which it is attached broken away.

Referring to the drawings:

10a indicates the supporting plane, which may be constructed in any suitable manner.

11 indicates the front portion of the machine and 12 the rear portion and 13 the aviators seat.

14 indicates the guiding plane which is mounted so as to be adjusted at various angles to the horizontal for guiding and steering the plane in any desired direction.

The rear portion 12, of the plane is formed hollow and has its rear end closed by means of a member 15, which is formed in two sections, each section being secured to the body portion 12, by means of rivets or bolts 16. VJhen the two sections 15, are connected as described, an opening 17, is provided in which the stem or shank 18, of the steering plane is located. The opening 17, and stem 18, being so arranged and proportioned that this stem may move upwardly and downwardly therein, and also rotate. Mounted in the rear portion 12, is a bracket 19; carried by the bracket 19, is a head 20, which is connected to the bracket by universal joint or connection 21.; Formed integral, with the stem Y18, is a member 22, provided .with arms 23 and 24; `mounted on the head 20, is a steering lever 25, which is free to move vforwardly and rearwardly on a pin 25a. By means of the universal joint 21, thehead 20, may be rotated, rand the steering lever 25 `can be moved laterally. Mounted in the member 22, is an end piece 26, the same being secured to the member22, by means of pins 27, mounted in slots 28, formed in the .member 22. Connecting the head 20, and the end piece 26, is a skeleton member 29, formed of strips of light metal,`

riveted together so as to form a lattice work .member This member 29, is so constructed that it is very light and strong. 8O indicates a link which is pivotally connected to the arm 23 and the steeringflever 25; andv 31 indicates a. similar link which is pivotally connected to the arm 24, and also the lowerv end of the steering lever 25. By means of this connection, by pushing forward on the steering lever, the steering plane 14, can be elevated as illustrated in dotted lines in Fig. 2, and the opposite movement ofthe lever 25, the steering plane may be tilted downwardly as is also illustrated in Fig. 2.

As previously pointed out the head 20, may partly rotate in the bearing'21, and by operating the hand lever laterally the, steering plane 14, may be adjusted laterally to-V ward the horizontal. 1

1n Fig. 3 l have illustrated the maximum adjustment of the steering plane when the machinei is in flight,.in descending toward the right;l and in Fig. 4.1 have illustrated the maximum adjustment ascending toward the right.

It is understood of course, that by the construction shown and described, the steering plane 14, may be` brought to diierent adjustments which can be performedbythe manipulation of the single steering lever 25.

Mounted in the rear portion l2, ofthe machine, ina suitable slot provided therefor,

is a guiding plane 32, which is pivotally connected andarranged to rotate with the mem ber 29. Y A

In Fig. 7 I have shown the guiding plane 32 in an operative position, occupyingthe vertical position; and in Fig. 8 it is shown in an inoperative position. Y

This plane is used when it is desired to fly straight in a horizontal direction, so as to steady the machine. The downward movement of this guiding plane 32, is limited by stop arms 33.V

The operation of my improvement is as follows:

In flight in horizontal direction the steering plane 14 is adjusted as shown in solid lines in Fig. 3, by means of the steering lever 25, if it is desired to descend toward thev right, and by means of this lever said plane is adjusted asillustrated in dotted lines in Fig. 3, if it is desired to descend toward the left. If it is desired to ascend while in flight, toward the right, the plane is adjusted as illustrated in Fig. 4; and to 'ascend toward the left, as shown in dotted lines 1n Fig. 4.

VIt will be observed that by pushing the lever 25 forward and toward the side to; the righttwo movements or adjustments is given the plane 14; that is to say, it 1s tilted forwardly and simultaneously laterally, and it said lever is pushed forwardly and simultaneously to the left, the plane is tilted upwardly and forwardly and simultaneously inclined laterally toward the left. v

Having fully described my invention what I claim is: Y

l. An aeroplane'comprising a body portion and rear tubular portion, a partially rotating rigid skeleton member located within the tubular portion having one end pivotally mounted therein, ya hand lever pivotally connected thereto, a guiding plane mounted in the rear end of the rear portion and pivot-` ally connected to one end of vthe skeleton member and capable of verticahtandlateral adjustment,` and a connection between said guiding plane and hand lever whereby the said guiding plane may be vertically and laterally adjusted simultaneously.

.2. An aeroplane comprising a tubular portion, a rotating rigid member located within the rear portion and having its front end pivotally supported therein, a guiding .plane pivotally securedto the rear end of sald rotating rigid member, a hand lever pivotally secured to the rotating rigid member located in the rear portion, and a link connection between the guidingplane and hand lever, and a guiding plane .pivotally secured to said rotating member and l`capable Vof being thrown into operative and inoperative posiv.tion by the rotation of the. rotating rigid membermounted in the tubular portion.

3. An Vaeroplane comprising aV body portion, a tubular rear portion, a rotatingn meinber located within the rear portion, a steering plane pivotallyV secured to said rotating member,a hand lever pivotally secured to ally secured to the hand lever and steering plane, a guiding' plane passing through the wall of the tubular portion and pivotally secured to the rotating members, said guiding plane adapted-to be withdrawn out of' operative position and extend into operative position by the rotation of the rotating member. i

4. An aeroplane comprising a tubular rear portion, a support within the tubular rear Vtubular portion, a pivoted hand lever carried by the'rotating member, a guiding plane pivotally secured to the rotating member, and stop arms carried by the guidingplane.

5. A'n aeroplane comprising a reartubular portion, a rigid skeleton member having one ,said rotating member, a pair of links pivotof its ends mounted for rotation within said rear tubular portion, a yoke pivotally Vand adjustably carried by the opposite endo said rigid, skeleton member, a guiding plane carried by said yoke, a hand lever'pivotally secured to the forward end of the rigid skeleton member, a link disposed on opposite sides of the rigid skeleton member and having its ends pivotally secured to the yoke and hand lever,and a guiding plane'mounted withinan opening formed in the rear tubular` v portion and pivotally connected to the rigid skeleton member and capable of being oper-- ated upwardly and Vdownwardly by the rotation of the rigid skeleton member' and stop arms carried bysaid guiding plane to limit the downward movement thereof. Y
